Detailed Description

The objective of the present study is to determine whether intranasal oxytocin (IN-OXT) effects on blood oxygenation level-dependent functional magnetic resonance imaging (BOLD fMRI) in the amygdala vary as a function of dose and latency. In particular, the investigators plan to compare effects of three different IN-OXT doses (12, 24, and 48 international units, IU) and three different dose-test latencies of IN-OXT administration (task starting at 15, 45 and 75min after administration) on established neural and behavioural correlates of emotion processing. As effects of OXT are particularly promising in autism, the investigators further want to investigate how autistic-like traits influence the OXT effects in exploratory post-hoc analyses

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Neural substrates of emotion processing, measured via blood-oxygen-level dependent signal in the amygdala
Time Frame: 45min after nasal spray administration

Magnetic resonance imaging (MRI) will be performed to measure blood-oxygen-level dependent signal in response to emotional face stimuli of varying intensity. The investigators specifically plan to investigate amygdala response to fearful faces, as this subcortical region has repeatedly been reported to show activation changes after OXT treatment.

Dose-test latency varies between the different treatment arms (i.e. imaging starts 15min [arm 1], 45min [arm 2,4 and 5] or 75min [arm 3] after nasal spray administration).
45min after nasal spray administration

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Ratings of emotional faces
Time Frame: 45min after nasal spray administration

During each trial, subjects are asked to use a button response grip to indicate whether they perceived the depicted face as neutral, fearful or happy.

Depending on the treatment arm, ratings are recorded 15min (arm 1), 45min (arm 2,4 and 5) or 75min (arm 3) after nasal spray administration.
45min after nasal spray administration
Questionnaire measurement of mood (PANAS)
Time Frame: 10 min before and 105 min after nasal spray administration
Positive and negative affect is assessed via self-rating questionnaire 'The Positive and Negative Affect Schedule' using a categorical 5 point scale.
10 min before and 105 min after nasal spray administration

Time Frame: 10 min before and 105 min after nasal spray administration
State anxiety is assessed via self-rating questionnaire 'and State Trait Anxiety Inventory' using a categorical 4 point scale.

Plasma oxytocin concentrations
Time Frame: immediately before the nasal spray administration and immediately after the fMRI experiment

Modulatory effects of autistic like traits on neural and behavioral outcome measures
Time Frame: screening session, ~7days prior to imaging session
Autistic like traits are assessed via Autism Spectrum quotient in a screening session, preceding the testing sessions. The investigators expect pronounced OXT effects in subjects with high autistic-like traits.
